CHARLES F. BRAND, OF WHEELING, WEST VIRGINIA.

GAS-BURNER.

To all whom it may concern:

Be it' known that 1, CHARLES F. BRAND, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and State ofWest Virginia, have invented certain new and useful Improvements in Gas-Burners, of which the following is a burners carried thereby or alternate burners only, as desired. I

With these and other important objects in view, the invention resides in the fea tures of construction, arrangement of parts and combination of elements which will hereinafter be fully described, reference being had to the accompanying drawings,

in which Figure 1 is a side elevation of the invention, showing some of the burners omitted from the manifold;

Fig.2 is a partial horizontal section ofthe manifold; and- Figs. 3' and 4 are sections taken respectively on lines 3-3 and 4-4, Fig.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views 1 indicates generally a manifold consisting 'of a circular one-piece metal casting which is cored out interiorly to provide two separate chambers 2 and 3. Said chambers are located in superposed non-communicating relation, being separated throughout by the two passages 18 are designed to receive a horizontal division wall 4. Said chambers are further located annularly with respect to a central" hub-like portion 5 of the casting, being disposed between said portion and a circular vertically-disposed web 6 which is located concentricwith respect to 'said hub-like portion and at a suitably spaced distance from the outer peripheral wall 7 of the casting.

Leading vertically to the interior of the lower chamber-7.3 through the bottom wall 8 Specification of Letters Patent. 7

of the casting is a threaded hole 9 in which is received the upper end of a pipe 10 which constitutes a branch of a gas-supply pipe 11; and leading upward to the interior of the upper chamber 2 through said bottom wall 8,'the division wall 4 and anintegral tubular member 12 located between said walls 4 and 8 is a passage 13, threaded at its lower end, in which is received the upper end of a branch supply pipe 14.

The peripheral wall 7 of the manifold has extending therethrough a plurality of uniformly spaced radially directed threaded openings or holes 15 adapted for the reception of the threaded inner ends of suitable individual gas burners 16, or of short lengths of pipe 17 'upon which said burners are mounted, said manifold being thus adapted to be encircled by a cluster of burners. Said holes 15 communicate at their inner ends'with passages 18 alined therewith which are located between the circular web 6 and the peripheral wall 7 and which are separated by vertical radially disposed webs 19 which extend from the top wall 20 to the bottom wall 8. Said passages, except two diametrically opposite passages 18*, Figs. 2 and 4, alternately communicate with the chambers 2 and 3 through passages 2 and 3*, as shown in Figs. 2

and 3.

Formed on the top wall 20 of the mani- 7 fold is a diametrically disposed rib29 which is cored out interiorly to form a passage 21 which communicates at its opposite ends with the opposite passages 18, hereinbefore referred to, through ports 22 formed'in said top wall.

Leading vertically upward through the central hublike portion of the manifold and communicating at its upper end with said passage 21 is a central bore 23 which is threaded at its lower end for the reception of an end of a branch supply pipe 24.

The holes 15 which lead outward from 14, respectively, whereby the supply of gas through said pipes may be regulated or en- 'to the pilot burners.

tirely shut off. Or, a thermostatically controlled valve, as the snap valve 27, may be provided on the supply pipe 11 whereby regulation of the gas supply may be controlled. A valve 28 may be provided on the pilot supply pipe 2 2 to be closed when use of the heater is discontinued. 'lVhen the thermostat-controlled valve 27 is employed, the same is located forward of the point of attachment of the pilot pipe 24 with the supply pipe 11, as shown in Fig. 1, so that the supply of gas furnished through said pilot pipe will not be affected by operation of said valve.

burners 16 maybe employed. With twenty-.

four burners mounted on the manifold, as

shown, in Fig. l, the entire number may be 20 utilized for furnishing heat; or, by'shutting off the two pilot burners, the number may be reduced to twenty-two. lVith the valve 26 closed, cutting off the burners supplied through the upper chamber 2, but fourteen burners are supplied, and this may be re duced to twelve by shutting off the supply With the valve 25 closed, cutting off the burners supplied through the lower chamber 3, twelveburners are supplied, and this may be reduced to ten by shutting off the supply to the pilot burners. Or, both valves 25 and 26 maybe closed,leaving only the two pilot burners lighted.

The three branch pipes .10, 14 and 24 serve as supports for the manifold which is mounted directly thereon. V

Among various advantages affordedby the manifold described, one of the mostimportant and'one which instantly appeals 'to those skilled in the heating art is the ease and facility with which it may be installed, as compared with the burners commonly employed.

What is claimed is- 1.1 A multiple-burner manifold for furnaces, comprising a body having therein separate inclosed chambers located in superposed relation at a suitable distance from its outer edge wall, said edge wall havingtherein a plurality of holes adapted for the reception of individual burner elements, an inclosed radially disposed passage for each of said holes and communicating with the latter at its outer end, said passages having alternate communication at their inner ends with the upper and lower of said chambers, and separate supply passages leading to said chambers. v

2. A multiple-burner manifold for furnaces, comprising a 'body having a central hub-like portion encircled by separateinrality of radial openings for the reception of individual burner elements, separate radially disposed passages with which said openings communicate, alternate passages being in open communication at their inner ends with the upper and lower of said chambers respectively, and separate supply passages leading to said chambers. r

3. A multiple-burner manifold for furnaces, comprising a body having a central hub-like portion encircled by separate inclosed chambers located in superposed relation and at a suitable distance from its outer edge wall, said wall having therein a plurality of radial openings-for the reception of individual burner elements, separate radially disposed passages with which said openings communicate, one or more of said passages being adapted to supply pilot burnerstherethrough, means for conducting gas to the last-mentionedpassages, the remainder of said passages communicating at their inner ends with the upper and lower of said chambers in alternation, and separate supply passages leading to said chambers.

ers therethrough, said hub-like portion having a passage therethrough adapted for the reception of an-end of a supply pipe and communicating suitably with the last-men tioned passages, the remain'derof said passages communicating at their inner ends with the upper and lowerof saidchambers in alternation, andseparate supply passages leading to said chambers.
